Washer jet issue

Drivers side.
Took it out back to the Y tube, short length is fine, spilt the jet from the 90 bend and what turns out is a rudimental non return piece?
Freed the ball bearing as it was jammed solid and can feel it 'breathing through' when I blow on it, with the ball bearing at either end now.

Bearing occasionally jams, is that fine as it still blows...?
anyhow putting it back together I take it the arrow on the non return piece needs to point to the jets...didn't see it until I had it in bits...
